One-Push Button Pocket WIFI

We need a secure, easy to use mobile WIFI that we can bring anywhere. These are the things I would like for a prepaid pocket dongle:

-Dual-SIM: Where you can use any provider you want, prepaid or postpaid.

-One-push button load: We know that Amazon championed the Dash buttons where you can buy laundry soap at a push of a single button, and they will deliver it to you. When your mobile data is empty, you can just fill it up by a similar one-push button. That’s convenience! (mostly for emerging markets).
